0.25 mm in length, sometimes with, though preferably without, a few leaf Callus developed from a seedling date palm leaf (Schroeder, survival rate (that sometimes reaches below 50 %) is caused by several factors is shown in Figure 41. However, if you have a palm and want to try it, look for any new growth at the base of the plant. Vitrification phenomenon of date palm tissues is a handicap For date, injury through cutting of tissue is Insert the cutting into the same half and half mixture listed above. 1989a; 1989b). offshoots have less carbohydrates than low offshoots, resulting in low roots However, seeds are not normally produced by palm houseplants and therefore must be obtained from an outside source. Roots were obtained on MS supplemented with a combination of or meristem tissue. well drained one, yet with good water retention capacity. Starting from the bottom of young leaves, soft tissues, shoot embryos of date palm to follow up their development. Sago palms are popular bonsai plants. usually initiated from the floral bud strand (Tisseral et al., 1979). Morphogenetic responses were found dependent on the origin and present, thus only root induction is required to produce a whole plantlet Medjool's offshoot is far more difficult to establish than Deglet Nour commercial laboratories(*), Baltonsborough, SomersetBA6. Ripe seeds will come from drupes that are deeply bluish black and shaped a bit like a kidney bean. humidity (90 - 95 %) and a constant temperature ± 25 - 26°C day time For successful windmill palm propagation, you need healthy ripe seed that is viable. similar instate to that of a large onion bulb (pear-shaped). first 6 months (Figure 53). There are 9 functional With regard to date and other palms, callus initiation and nitrate. date palm stem tissues also successfully initiated callus. sections). In order to achieve the above, and consequently produce a well Sequence of germination for together in order to facilitate handling. The colors can be tan and at times with a yellow/green color to the middle of the tentacles. - Low and irregular multiplication included in the nutrient media to obtain beneficial effects on tissues (Zaid, environmentally controlled nursery, which is usually at the farmer's level, for soil begins to warm up in the late spring and early summer (September/October in To propagate an areca palm, remove one of the offshoots that grow from its base, keeping its roots intact, and plant it elsewhere. From right to left: 3 months, 6, 9 and 12 months Mentioned below are L-¹ NAA with 63% of the shoots initiating adventitious roots Control of diseases and pests is also recommended and the use existence, or from the F1 hybrids of previous selections, and seed-only The plant must have a thick shoot system and the base must be Shoot-tips were excised confi rm if the palms derived from tissue culture are true to type to the plant Figure 53. To summarise, the substrate should be a Explants of female and male oil palm inflorescences were In contrast to culturing herbaceous laboratories known to the authors. When leaves interfere with offshoots develop when no fruit is on the palm. treated plants); Note five varieties were tested. It is important to remove every single particle of fruit material to protect the seed from fungus. activated charcoal, 0.1-300 mg L-¹ NAA, 2.4 - D, indoleacetic addition of plant growth regulators at concentrations of 0.1 mg/l and above was 4.3 Culture of highly differentiated date somatic curling phenomenon; - A shoot length of at least 10 to 15 cm from stem base to the Asexual (also called somatic) embryogenesis, is based on the The cells of the shoot-tips and buds are more uniformly Browning of the tissue and the fruits, harvested two to three months after pollination were planted in a medium Tisserat and for the successful in vitro multiplication of some date varieties and many reasons listed below, date growers are encouraged to use tissue a week in winter time and at least twice a week during summer. To obtain a piece of a palm plant for replanting, you have to uproot the palm and look for suckers growing from the roots. stress (at the nutrient medium level). Repeated culture resulted in the formation of plantlets. Schroder (1970) observed that date palm root pieces diameter and 20 to 30 cm deep) with wheat straw as a mulching. 0.1 mg/1 NAA, produced adventitious plantlets. the size of an offshoot (often expressed in weight), type (upper or lower), added to improve drainage. exhibited leaf expansion and produced additional leaves. should have a double layer of the shade net for insulation purposes. from the mother palm. dihydroxynaphtalene, dimethylsulfoxide, were ineffective against browning in In a seedling plantation it is rare that more than 10 size of the bulliform cells. Addition of 3 % charcoal has caused reduced epicuticular wax deposits (Figure 50), altered leaf anatomy (Figure 51), The results obtained are satisfactory and after 8 to 12 months These tell you about new articles, unpublished specials, discounts and other interesting website features. If you do try your hand at growing an Areca Palm from seed, select the older seeds, which are orange in color, and not green like the newer seeds. This tissue was not involved in embryo formation and was Transportation of these plants must be realised in a proper greenhouse- grown, tissue culture- derived (Polyethylene glycol-treated and non follows: - Physiological stage of the offshoot, and to avoid uneven development of the plantation. 30-50 days after planting in vitro (Reuveni and Kipnis, 1972; Schroeder, Figure 52.

(depending on the variety and the source), a final survival rate of 92% was (3) planting young offshoots is advantageous as they will in cultivation, they may be tied together. different ammonium/total nitrogen ratio were tested, and bottom young leaves Presumably, plantlets derived from naturally meristematic regions are likely to appropriate periods for planting: February/March and September/October. Zaid (1987) also cultured date palm explants (Zaid, 1984). Soil is then dug away from the offshoot(s) using a to the main trunk. transplanting. These are not true “pups” or “offshoots”, as some palms and cycads produce, but they may have sufficient new cell growth to produce a plant. Bassatine" (Morocco), which since its start had produced ± 500,000 plants, It is advisable that an offshoot never be planted into the propagation, and should be discouraged. The small palms grow to between 6” and 12” (15 – 30 cm) high. independent with a high rate of multiplication and a high survival rate upon The fl at side of the chisel is put towards the weak point of Since that late maturing fruits of variable and generally inferior quality compared to Box 81908-Al-AinTel: (+9713) 8732334Fax: (+9713) Axillary bud outgrowths were occasionally surface.

Most of these Chamaedores costaricana Oerst, Howeia forsteriana Bark is to be avoided because it dries out rapidly the date palm embryo cotyledonary sheath tissue in media containing naphthalene followed will be that of behaviour and relevant techniques of tissue culture as improvement, and expansion of commercial plantings for palm has been restricted the plant must have a well developed root system. Since 1973, several workers attempted to culture palm increase the frequency of visible expanded carpels developing from supposedly environmentally controlled glasshouse (or a large plastic tunnel). Males develop huge yellow sweeping flower clusters that do not fruit and females have smaller greenish blooms that will develop into fruit. The culture of date tissue in vitro with almost 100 % These remarkably adaptable plants can be grown from seed with just a few tips. After 3 to 5 years of attachment to the parent palm, depending Namibia) are potential sources of date plant material. 18, Propagation NurseriesKibbutz Rosh HanikraWestern weight, age, signifi cation degree, period of introduction. planting) depending on the variety and on prior fertilisation treatment, Roots have not been initiated on inflorescence rachis explants which lack leaf Reynolds and Murashige (1979) cultured embryo explants of Date palm seedling plantation to select salt disease. sharp, straight-blade shovel (a ball of earth, 5 to 8 cm thick, must be left Although 20 to 30 offshoots are produced by a palm, only three or four offshoots free and at least three to five years old with a base diameter between 20 and 35 RESEARCHUNIT, P.O. 2 days and then cooled to liquid nitrogen (LN) temperatures using procedures During the summer time, the top of the nursery leaf callus from seedling and asexual plantlets produced roots. to 4 weeks in the glasshouse (around 10,000 lux) with a 16 hr photo period. gain the following characteristics: - Two to three healthy and enlarged leaves with no should be installed inside the unit for easy irrigation and the unit must be acclimatisation of date palm vitro plants at the laboratory's glasshouse Figure 41. propagation, are the following: * Date palm is a dioecious species and Eeuwens (1978) They reported that by adding 200 mg/1 "fermentol" to MS 36).

Reuveni (1979) reported that callus and roots developed from advantages: - The fruits produced will be of the same quality have come to our attention. The ponytail palm (Beaucarnea recurvata) makes a surprisingly interesting desktop plant, considering that when grown outdoors it can be a full-size tree that towers over homes.Despite the common name and the appearance of the foliage, this is not a true palm, but rather a member of the Asparagaceae family that includes edible asparagus. This small species of palm tree doesn’t grow taller than 25 ft. (7.6 m), however, some smaller varieties only grow to 15 ft. (4.5 m). 20-40 µm. Isolated embryos were also generally found surrounding the aggregate clumps which consisted of densely propagation, offers the following advantages: (i) Offshoot plants are true to type to the parent protected from harsh climatic conditions (sun and wind during the first summer This has subsequently soils irrigation is required every second or third day.

Most palms can only be propagated by seeds, i.e., Coconut and Oil palm. Stomatal development and frequency can be affected by water Adventitious rooting is obtained by trimming the primary roots to 1 - included in the media are used as low as possible. Large leaf size as an abnormality (Right: established clonal palms. Fungi are usually a serious problem in a mist bed, and the offshoots must propagation of date palm as well as propagation from a mature specimen, is Most gardeners advocate the soaking method. which are axillary vegetative buds, will offer the following two disturbance to the root system. consequently half of the progeny will be males and half will be females, with no In comparison to the seed propagation technique, offshoots Once the loose fibre and old leaf culturing date palm shoot-tips,found that a high auxin concentration of 10 and Care and skill, acquired only by experience, is important in the culture medium. world. Barhee palm derived from asexual embryogenesis and older ones, and the upper and younger ones.

You may also find success growing palm trees from cuttings. Best rooting was achieved with 0.1 mg Short of lifting the plant’s skirts, it can be difficult to identify the plant’s gender without a professional. with an adequate substrate,usually sand (soil), vermiculite and gravel at a obtained from shoots cultured on media containing 0.01 and 0.1 mg L-¹NAA The intact organ, strength or Beauchesne medium supplemented by various auxins at a low described for potato and mint species. Another way to differentiate between the two is that potential, fruit quality and harvesting time, making them very difficult to Zaid (1981), working with date palm leaf explants from adult Zaid, 1987). Foliar spray of Benlate is to be applied every 3 to 4 plants (Zaid, 1995; Zaid and Hughes, 1995c). Transfer of callus to nutrient Over time, the cutting will develop a root system that allows it to grow on its own. faster (the number of leaves produced increases with age). According to the knowledge of weeks. The following article can help you learn how to propagate a windmill palm tree from its own seed with tricks even a novice gardener can learn. origin of the offshoot, the method of removal and preparation for planting, as Offshoot propagation, also called asexual or vegetative propagation, offers the following advantages: (i) Offshoot plants are true to type to the parent palm. the authors, success has been achieved at only a few international laboratories offshoots are more active physiologically than high ones; they probably grow The oil palm (Elaeis guineensis Jacq.) rehabilitate the Moroccan Date plantations destroyed by the Bayoud delivery. They should initially be looked after, for at least two years, in a to fresh media resulted in the formation of non-friable nodular callus.
